Coal is an important energy resource for meeting the further demand for
electricity, as coal reserves are much more abundant than those of other fossil
fuels. But, coal utilization technology produces carbon dioxide more than other
fossil fuels, because of the higher carbon content of coal. For the control of the
global warming problem, it is required to develop a new technology for the
reduction of carbon dioxide emission from coal-utilized power stations.
To reduce carbon dioxide emission, it is very important to develop a new
technology of high efficiency power generation system and utilize biomass
energy of carbon neutral. For the further reduction of carbon dioxide, the
removal and storage technology is an effective one. It is necessary to apply the
smart process of powder technology for the development of coal utilized power
generation system of new type including a high efficiency power generation
system and carbon dioxide removal type power generation system. For the
utilization of biomass energy, it is very important to develop the smart
technology for the handling of biomass like drying, carbonizing, pulverizing and
conversion technology.
In this paper, many technologies for the powder handling related to the high
efficiency coal utilized power generation, biomass utilization and carbon dioxide
removal power generation are introduced. Furthermore, the present level of these
technologies and the development tendency for the future are surveyed.
Keywords: coal utilization, carbon dioxide, biomass, low rank coal, high
